Application filed April 28, 1910. Serial No. 558,143.

To all whom it may concem:

Be it known that we, WILLIAM Toner and ALrnno J. ToBEY, both citizens ofthe United States, residing at Iola, in the county of erators and moreparticularly to a device especially adapted for sup lying gas lampsonautomobiles or other ve icle I The principal objects of our inventionare ene gas generator having alar e eneratin ca acit in ro ortion to itssi hey which 5111 riot germit le akage of gas; which will deliver thegas in a comparatively dry condition, and in which the carbid is heldout of contact with the outer shell of the ap aratus.

A further 0 ject of the invention is to provide the improved'details ofstructure hereinafter described and pointed out in the claims, referencebeing had to the accompanying drawings, in which Figure I is aperspective view of a complete generator embodying our invention. Fig.II is a vertical longitudinal section thereof, indicating the water inthe left hand chamber. Fig. III is a cross-section upon the line IIIIIIof Fig. II. F ig IV is a perspective view of the carbid and ash holder,a part of'theremovable head being broken away. Fig. V is a detail view,partly in section, of the gas duct between the generating chamber andthe hose nipple; the carbid holder being removed.

Referring more 1n detail to the parts The outer shell of the generatoris composed of two container parts, 1 and '2, the open ends of which arefitted against opposite sides of a metallic partition 3 and providedwith 1gaskets 4, for forming tight joints, the perip cry of thepartition 3 being formed with gasket grooves and with an exteriorannular flange 5, havinga pair of supporting legs 6.

The shellis made of special steel adapted to resist high internalpressures. Upon the shell member 2, near the end opposite the partition,is a two-part collar, composed of an up or half-7 and a lower half 8,said parts eing hinged together at 9 and"provided with registeringbifurcated lugs 10, 11. Pivoted between lugs 11 is a bolt 12 which isadapted for projection between the parts of the upper lug 10, and has anut 13 which may be tightened against the lug to hold the partstogether. The lower collar member 8 is provided'with legs 14, which,with the legs 6, are adapted to support the device on therunning-boardof an automobile.

Passing through central openings in the shell members 1, 2, and in t epartition 4, is a longitudinal bolt 15, having end nuts 16, betweenwhich and the shell members are located the soft washers 17, thepartsbeing so arranged that when the nuts 16 are pro erly tightened the shellsections will be he d firmly against the metal partition 3 and thedevice rendered gas-tight.

On the bolt 15, adjacentthe partition 4, is a collar 18, and betweenthis collar and the partition 4 is a compressible washer 19, which formsa gas-tight seal around the bolt 15 to prevent leakage of gas' or airthroughthe partition, particularlywhenthe generator portion is removed.

lVithin the large shell member 2 is acan 20, one head 21, of which isremovable and provlded w1th a flange 21 for fitting over .the sides ofthe can body, as shown in Fig.

IV, both of said headshaving central openings, through which the bolt 15may pass.

'In the side of can 20 is a lon itudinal opening within which is fixedpreferably by soldering) a trough 22,.which trough projects into thecan, and has perforations 23' in its bottom. Within the can and restingon brackets 20 is a horizontal grating-24, preferably of wire cloth.Formed in the partition is a duct or passa'ge.2$) which afi'ordscommunication between the tubes 25 and 27, and projecting into said ductis a needle valve 30, for regulating the flow therethrough.

25 designates a water supply tube, one end of which is threaded into theend of duct 29-that opens into the gas chamber, the body of the pipebeing extended within the trough 21, and provided with a row ofperforations 26. p

Located in the air and water chamber, within shell member 1, is a tube27, the upper end of which is threaded'into the end 2 drops upon the ofduct 29 and having its opposite end opening into chamber 37 The lowerend of this tube is positioned close to the bottom of the chamber and isprovided with a ball check valve 28, which operates as hereinafterstated. Threaded into the shell member 1, above the'water line,designated 31, is a nipple 32, and fitted into said nipple is an airvalve 33, through which air may be forced into the water chamber toprovide the feeding pressure, the valve being adapted for receiving thetube of an ordinary tire pump. In the top of the shell member 1, weprovide a gage, 34c, for indicating the air pressure in the waterchamber, and a similar gage is connected to the top of the shell member2 for indicating the gas pressure in the generating chamber 36.Connected to the-flange 5 is a hose nipple 38, which communicates .withthe interior of chamber 36 by way of a duct or passage 39 in the metalpartition 3, and connected to the nipple 38 is a. flexible tube 41 forleadi 'ig the gas from the generator. Duct 39'isi n ovided with a needlevalve 40 for coi'itrol-ling the flow from the generatorto the lamp. j

The mode of operation is as follows: The generator part 2 of the shellis opened, the can 20 removed from the shell, the head 21 removed fromthe can, and acharge of carbid placed on the grating 23. The can is thenclosed and replaced in the shell, and. the latter sealed up by means ofthe bolt 15 and nut 16. The chamber 37 is filled with water through thenipple 32, (after removing the valve 33) up to the water line 31, thevalve then being replaced. The rubber tube of an air pump isthenconnected to said valve, and air is pumped into the chamber 37. Whenthe air pressure has been supplied to chamber 37, the valve 30, whichshould be closed during the pumping action .in order to prevent a rushof water into the tube 25, is opened to allow water to be forced throughthe tube 27-, partition 4,

and tube 25 into the trough 22, from which it passes through theperforations 23, and -arbid, to generate the acetylene gas. When the gaspressure, as shown by the gage 35, approximates that of the air, thevalve 30 thay be fully opened,

of water will be cut off until sufi'icient gas has been drawn offthrough the tube 41 to reduce the pressure of the gas belowthat of theair.

Having thus described our invention, What we claim as new therein anddesire to secure by Letters-Patent 1s:-

1. An acetylene gas generator shell comprising an upright partitionplate havingsupporting legs; two cylindrical shell members, gasketsbetween the shell members and the partition plate, a concentricfastening bolt passing through said plate and the ends of the shellmembers, a twopart collar embracing one of the shell members, one partof said collar having supporting legs, and fastening means for the twoparts of said collar. Y

2.. An acetylene gas generator shell comprising an upright partitionplate having supporting legs; two cylindrical shell mem bers, gasketsbetween the shell members and the partition plate, a concentric;fastening bolt passing through said plate and the ends of the shellmembers, a tw'o-partcollar em bracing one of the shell'members, theparts of said collar being hinged together at one side and. providedwith a fastener at the op-' posite side. I

An acetylene gas generator comprising two outer shell sections, meansfor securing the same together, a transverse partition between saidsections, a carbid can practically filling one of the shell sections, aperforated trough at the top of said can, a grating within the can, aperforated tube withinsaid trough, an air admission valve upon the othershell section, a tube connected with said partitioi'i and extendingdownwardly toward the bottom of the last named shell section, and acheck-valve connected to or into said last named tube.

In testimony whereof we aflix our signatures in presence of twowitnesses.
